Abstract: For the production of oxygen from water by means of a thermochemical cycle, the hydrolysis of magnesium chloride in a gas stream in the temperature range of 200$^\circ$ - 600°C and the chlorination of the produced substance with a magnesium hydroxide chloride content of 97.8 % haue been investigated. Besides these gas-solids reactions, the conversion of magnesium hydroxide chloride and magnesium oxide with chlorine in an aqueous phase has been accomplished, too. The magnesium perchlorate-containing solutions obtained were decomposed at temperatures of 368° - 628'C with simultaneous oxygen production. By repeated chlorination of the residues in an aqueous phase a magnesium perchlorate solution was regained, which Ilkewise produced oxygen by pyrolysis with yields between 61.0 % and 92.2 %. The feasibility of this closed half-cycle with one solution reaction Gould thus be demonstrated successfully under recycling conditions.
